I'm also concerned about how hot the 986 engine can get. Not suggesting these to anyone, but I have bypassed the fan relays and wired a switch for each fan so I can manually control them. Why two switches?? Each fan draws 40 watts. When I tried a single switch controlling both it got so hot it melted.
I turn the fans on when the water temp gets to about 170 (low temp T-stat is open). The car never gets above 190 now.
